压缩文件中是C语言常用函数的PDF文档，非常全面，可以满足工程人员的大部分需求。-compressed files is common C language function PDF files, a very comprehensive, engineering staff to meet the needs of the majority.

应用背景应用于数理统计，能够将需要的数据再spss中计算好，计算出相关的系数，然后在程序中代入系数，即可算出多元回归的结果，改程序较EXCEL中计算尤为方便，可以提高工作效率。关键技术关键技术，改程序结合了SPSS和C#源码编程，能够直接将SPSS中计算出来的系数导入C#中，然后计算出经过多元线性回归拟合后的结果，计算非常迅速，方便，易于操作，从很大程度上提高了工作效率。
